> cassandra-stress should output some aggregated statistics for the data that it outputs. In testing the performance of a Cassandra cluster it's useful to look at the performance by establishing what the average read/write rate is during the middle 80% of a stress job (the first and last 10% being outliers as the cluster is starting and stopping a big operation.)
> I've implemented this to add these stats to the end of the cassandra-stress output. It also adds a command line option to turn it off if it's not desired.
> My branch here: https://github.com/EnigmaCurry/cassandra/commit/157993d087015b17267e613a458d5bc8bd36a888
